I bought Cobalt a new 2.5 gallon tank earlier today at PetSmart. After everything was set-up, I place Cobalt in the tank. Unfortunately, he went into shock and has passed away. I am very sad. He had a beautiful deep blue color and was a lively crown-tail Betta fish. I only got him last week.
I don't know what I did wrong? Someone from the BettaFish.com community tell me what to do so that the next Betta Fish I get will not pass away so suddenly.
I am so sorry Cobalt that I did this to you.
The 2.5 gallon fish tank that I got was made by Aqueon -- it is the one that has the light bulb and the filter.
